7 Installation and electrical connection
The installation and electrical connection work must be done in accordance
with local regulations and only by qualified personnel.
WARNING! Risk of personal injury
The accident prevention regulations in force must be observed.
WARNING! Danger of electric shock
Danger from electrical current must be eliminated.
Instructions of local or general regulations (e.g. IEC, VDE, etc.) and local
utilities must be observed.
7. 1 Installation
• Switch off the plant/switch cabinet at the mains.
CAUTION! Risk of damage to the interface converter
• The interface converters are snapped on to a DIN rail (DIN EN 50 022-35).
• Connect 24 VDC power supply to the AnaCon interface converters (Fig. 2).
NOTE: If there is no 24 VDC power supply available in the switch cabinet, a
separate power supply unit has to be installed in the switch cabinet with the
corresponding output voltage.
The output current of the power supply unit depends on the number of AnaCon
components to be connected.
• Connect pump(s) with PLR interface to the interface converter(s) (Fig. 2).
NOTE: if interface converter and pump(s) are supplied with voltage, the data
transfer via the PLR interface is started automatically.
If no current pump-based values are set at the interface converters, the factory
pre-set values will be sent to the pump(s).
• If not pre-wired in the switch cabinet, connect control and signal contacts and
also analogue signals to the corresponding terminals.
• Identification of the interface converters
NOTE: The AnaCon interface converters have an identification surface (20 mm
x 10 mm, Fig. 1, item 22), on which the component reference according to the
plant diagram can be indicated directly. Alternatively, a sticker can be applied to
this surface.
